Abstract

A capacitor charging apparatus includes a transformer and an output capacitor charged with current flowing through a secondary coil of the transformer, and charges the output capacitor by performing a switching control of a switching transistor provided on a path leading to a primary coil of the transformer. A switching control unit controls on and off of the switching transistor. A voltage detector monitors a voltage at a tap provided in the secondary coil of the transformer. The switching control unit regards the voltage detected by the voltage detector as an output voltage of the capacitor charging apparatus, and controls the on and off of the switching transistor.
